从httpmultipart请求获得xml响应

问题描述:

我有一个web服务,可以接受带有多部分的文件(在c#中),当我通过铬扩展名(高级休息扩展名)发送大文件(15MB)时,文件上传正常,我可以看到身体反应:从httpmultipart请求获得xml响应

<response xmlns="http://schemas.datacontract.org" xmlns:i="http://www.w3.org/2001/XMLSchema-instance"> 
<Descripcion>blabla</Descripcion> 
<Resultado>-9999</Resultado> 
<Servicio xmlns:a="http://schemas.datacontract.org" i:nil="true" /> 
</reponse> 

但是,当我与Android调用我得到一个200码OK响应头,但我不知道我怎么能得到身体的反应:

这是我的代码:

/****** Informacion exif *****/ 

       DefaultHttpClient mHttpClient; 
       HttpParams params = new BasicHttpParams(); 
       params.setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1); 
       mHttpClient = new DefaultHttpClient(params); 
       HttpPost httppost = new HttpPost("HTTPS://SERVICIO.SVC"); 
       httppost.setHeader("Connection", "Keep-Alive"); 
       httppost.setHeader("SOAPAction", "http://tempuri.org/Service1"); 
       httppost.setHeader("identificadorGUID", Guid); 
       httppost.setHeader("numeroServicio", codigoServicio); 
       httppost.setHeader("coordenadaLatitud", latitud); 
       httppost.setHeader("coordenadaLongitud", longitud); 
       if (QUEES == 0) { 
        extension = "jpg"; 

       } 
       if (QUEES == 1) { 
        extension = "mp4"; 

       } 
       httppost.setHeader("cuando", cuando); 
       httppost.setHeader("tipoMultimedia", String.valueOf(tipoMultimedia)); 
       httppost.setHeader("extension", extension); 

       MultipartEntity multipartEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE); 
       FileBody fileBody = new FileBody(fichero, "multipart/form-data"); 
       multipartEntity.addPart("image", fileBody); 
       httppost.setEntity(multipartEntity); 
       try { 
        HttpResponse response = mHttpClient.execute(httppost); 
        HttpEntity resEntity = response.getEntity(); 
        if (resEntity != null) { 
         resEntity.consumeContent(); 
        } 
        BufferedReader reader = new BufferedReader(new InputStreamReader(response.getEntity().getContent(), "UTF-8")); 
        String sResponse; 
        StringBuilder s = new StringBuilder(); 
        httppost.getAllHeaders(); 

        while ((sResponse = reader.readLine()) != null) { 
         s = s.append(sResponse); 
        } 
        Log.i("Respuesta web service", sResponse); 
       } 
       catch (ClientProtocolException e1) { 
        e1.printStackTrace(); 
       } 
       catch (IOException e1) { 
        e1.printStackTrace(); 
       } 

崩溃:java.io.IOException:试图从封闭流中读取。

我如何获得解析它的响应? 谢谢

看起来像你不应该叫consumeContent(),直到信息被读取(鉴于它关闭流)。如果您使用4.1或更高版本,此方法已被弃用,并且你应该使用EntityUtils.consume(HttpEntity)

从它的javadoc:

这个方法被调用,以表明该实体的内容不再需要。作为此方法调用的结果,所有实体实现都应该释放所有分配的资源。内容流媒体实体也有望处置剩余的内容(如果有的话)。包装实体应将此调用委托给包装的实体。
